There are some methods in LayerRender$Frame which are accessed from the JNI, for which wrapper methods in principle could be generated, but which are currently not being generated. The generation of these methods was removed from the patches for Bug 913985 for causing intermittent test failures. (See: https://bugzilla.mozilla.org/show_bug.cgi?id=913985#c116 ) The methods in question, at time of writing, are: drawForeground drawBackground beginDrawing endDrawing If solved, this bug will enable us to remove 4 evil Proguard annotations. Perhaps not a priority.
